Answer: 119°
Step-by-step explanation:
From the positive y-axis, all angles are measured clockwise
PR = PQ + QR = 5[150°] + 3[60°]
X = 5*sin150 + 3*sin60 = <u>5.1</u>
Y = 5*Cos150 + 3*Cos60 = <u>-2.83</u>
TanA = X/Y
A = -61° = 61° East of South = 119° Clockwise
Therefore, the bearing of R from P is 119°
You distribute the 4 to both x and 5. 4 times x is 4x and 4 times 5 is 20. Divide both sides by 4. X=5
The numbers are 3 and -30 They multiply and give -90 And add to give-27
Answer:
Calculate the determinant. Calculate the matrix of cofactors. Transpose the matrix of cofactors to obtain the adjugate matrix. Divide each entry of the adjugate matrix by the determinant to obtain the inverse.
Square of quantity x plus three means : <span><span>x+3/</span>√</span>
quantity x plus eight means : <span>(x+8)</span>
quantity x minus two means : <span>(x−2)</span>
Therefore :
<span>f(x)=<span><span><span>x+3 / </span>√</span><span>(x+8)</span></span>×(x−2)
</span><span>R:x≥−3</span>
